Mould and mildew growth is much more prevalent in homes with high humidity levels or improper moisture control.

Certain types of mould can even be fatal or cause long-term, chronic health problems. If you live in a region with high humidity, this guide will show you how to remove the humidity from your furniture, textiles, and more.

How to identify humidity in your home

Before you can remove excess humidity, you need to recognize when levels get too high. Humidity levels can vary depending on where you live, current weather conditions, and how much ventilation you have. Ideally, the Consumer Product Safety Commission recommends a humidity level between 30 and 50 per cent. Comparatively, the EPA recommends levels between 30 and 60 per cent to reduce or prevent the growth of mould and mildew. If you are having trouble breathing or you’re sweating indoors even with the air conditioner on, your home humidity levels may be too high. If you’re having difficulty determining the humidity level in your home, a hydrometer can help. This device measures moisture levels in the air. You can find one easily online or at many home improvement stores to monitor the status indoors. You can also always contact a local inspector for a professional opinion.

How to remove mould and mildew from furniture

Too much humidity can cause your furniture to accumulate mould, mildew, and musty odours. Here are some tips to help you remove it.

Wood furniture. Wood and other hard surfaces can be cleaned much more easily than fabric. Clean your wood furniture by using a vacuum with a HEPA filter to eliminate any mould sitting on the surface, and always wear goggles, gloves, and a mask to avoid touching it or breathing it in. Wipe down the wood using a mixture of ¼ cup of bleach and one gallon of water with a non-abrasive scrubbing sponge or tool. Let the wood dry, then place it outdoors in the sun to dry completely.

Leather furniture. Removing mould from leather surfaces will release the spores into the air. Take your leather furniture outside on a dry, sunny day and wear eye protection, gloves, and a facemask. Using a stiff plastic brush, scrape off any mould or mildew that you can see. Next, wipe the furniture down using one part water and one part denatured alcohol. You can also treat the furniture with a leather-safe fungicide. Make sure everything is thoroughly dry before bringing it back indoors.

Knowing when to clean or when to dispose of furniture. There may be some situations where your furniture can’t be salvaged. Upholstery and foam can hold onto mould particles, and they’re often impossible to remove. Upholstered furniture with visible damage is not likely able to be saved. If you want to keep the furniture frame, consider having it re-cushioned and reupholstered by a furniture restoration professional. Plastic, glass, metal, wood, and leather furniture have a much better chance of being adequately cleaned and salvaged than fabric.

How to clean other surfaces, rooms, and household items

Other than your furniture, you’ll need to remove mould, mildew, and moisture from textiles and various spaces in your home.

Removing musty odours. Too much humidity and moisture can create an unpleasant musty odour in your home. Diluted bleach is a good way to remove unpleasant odours from hard surfaces. Make sure all surfaces are bleach-safe first so that it doesn’t cause discolouration or damage. Wash curtains and fabrics by soaking them in bleach for thirty minutes, then use your washing machine’s regular cycle on the hot water setting. Place them in the dryer immediately and use dryer sheets to freshen them up. A mixture of plain white vinegar and baking soda is another DIY household cleaner that can easily remove musty odours and mildew safely from materials like wood and tile.

Bathroom grout. To get rid of mould and mildew from bathroom grout, use a stiff-bristled brush and scrub it away with a mixture of distilled vinegar and baking soda. You can also use hot water, hydrogen peroxide, or Borax to get rid of stubborn mould on grout.

Household items. If mould or mildew isn’t too bad, you can remove it from mattresses with a mixture of rubbing alcohol and warm water. Vacuum the mattress, then scrub it away in a circular motion. Rinse it clean and allow the mattress to dry completely before using it. Even books can be affected by mould. To remove it, use a fine brush, soft cloth, or vacuum to wipe it away. Denatured alcohol dipped in a soft cloth can kill mildew on paperback books, but always make sure that wet books are entirely dried before removing the mould.

Walls and closets. Mould spreads quickly, so it’s likely affecting your walls and inside your closets. Mix Borax, distilled white vinegar, and water in a spray bottle for an easy DIY method that will make removing mould easy. Simply spray the walls or closet shelves with the mixture and scrub immediately with a clean cloth or soft brush.

Kitchen pantries, laundry room cabinets, and cupboards. Dark, damp areas are a magnet for mould and mildew. Remove everything from your pantry or cabinets before you begin cleaning. If you see anything that has been contaminated, it’s best to throw it away to prevent illness. Try a commercial cleaner specially formulated to kill and remove mould spores. You can also mix bleach or hydrogen peroxide with water to scrub it away. Repeat the process once more and dry it before putting food and cooking items back into the pantry or kitchen cabinets.

Hidden areas. Moisture and mould can lurk behind your furniture, in corners of the room, and under the windows. Follow one of the methods listed previously to clean these hard-to-reach areas. The key is to quickly identify areas where mould and dampness are present before it gets out of control.

DIY tips for easy fixes. If you notice mould or mildew, mixing vinegar and baking soda to make a household cleaner is a quick DIY fix. You can also remove mould by juicing a few lemons to make a DIY cleaner. Lemons break mould spores down and leave a pleasant scent behind. Let the lemon juice sit for five minutes, then gently wipe the area clean with a dry, soft cloth or stiff brush depending on the severity of the mould.

What to do to prevent it

Prevention is critical when it comes to removing humidity and getting better moisture control in your home. Here are some prevention tips to help you keep excess moisture at bay.

Vent your home properly. Make sure that your attic, basement, or crawlspace has ample ventilation. Bathrooms should also be adequately ventilated, and fans should be used whenever you bathe or shower.

Consider a dehumidifier. If humidity levels are too high, a dehumidifier can help to bring them back down. There are many types of dehumidifiers to choose from. They range from desktop models to whole-home solutions. Especially useful if you live in an area where humidity is practically uncontrollable.

Chemicals that absorb moisture. Some chemicals can absorb moisture in damp areas like a basement, kitchen, or bathroom. Silica, clay absorbers, and calcium chloride are all excellent options. Most are safe as long as they’re stored away from pets and children.

More prevention tips. An excellent way to reduce humidity levels is to keep the air in your home moving. Install ceiling fans in the home and keep your windows open on days when outdoor humidity levels are low. Prevent condensation from building up on windows and in the bathroom to control humidity and mould growth.

DIY vs calling the experts.  In most cases, you can remove mould and mildew yourself if it’s not too severe. However, if you suspect the presence of black mould or if the mould growth is too robust, it’s time to call in the experts for help.

Preventing moisture when living in humid climates. States like Florida have exceptionally humid climates. If you live in a primarily humid region, ensure that your home is well-ventilated and that your plumbing is in good condition. Leaking pipes can cause humidity levels to rise. A quality air conditioning system can keep your home cool and keep mould growth from occurring.

A few simple preventative measures can help you get the best moisture control in your home. Know how to recognize the signs of high humidity and mould growth so you can stop it before it gets out of control. With a few simple cleaning tips and some regular monitoring, it’s easy to live in a home that’s safe, dry, and free from mould and mildew.
